Several Ferrari-powered cars took on a range of new power unit components at the 2023 Austrian GP.
Additionally, reigning world champion Max Verstappen made use of his second and final control electronics on his home turf.
F1Technical’s senior writer Balázs Szabó provided insights into the engine situation from the Red Bull Ring paddock.
The current generation of Formula 1 power units comprises seven different elements: the internal combustion engine (ICE), motor generator unit-heat (MGU-H), motor generator unit-kinetic (MGU-K), turbocharger, energy store (ES), control electronics (CE), and exhaust.

Throughout the 2023 season, drivers are limited to using a maximum of four ICEs, MGU-Hs, MGU-Ks, and turbochargers, as well as two energy stores and control electronics.
They can have up to eight of each of the four elements that constitute a set of exhaust systems.
All four drivers racing for the customer Ferrari teams, Alfa Romeo and Haas, have received fresh internal combustion engines for the Austrian Grand Prix.
Interestingly, this will only be the third new engine for Valtteri Bottas, Zhou Guanyu, Kevin Magnussen, and Nico Hulkenberg, despite Ferrari’s reliability issues earlier in the 2023 F1 season.
Both Haas cars will be equipped with a new turbocharger, and the two factory Ferrari drivers will also receive a fresh TC.
This will mark the third unit for all four drivers, leaving them with one new component remaining for the rest of the season.
The same quartet will also utilize a fresh motor generator unit-heat in Austria, with one new unit still available for the remainder of the championship campaign.
Interestingly, all Ferrari-powered cars will feature a fresh exhaust system at the Red Bull Ring, as they have already used three EXs during the season.
Double world champion Max Verstappen will introduce a new energy store and a new control electronics into his pool of engine components.
This means that the Red Bull driver will aim to complete the season using both the previous and newly-installed units.

AlphaTauri’s Nyck de Vries and Yuki Tsunoda will receive a fresh energy store, with the Japanese drivers also obtaining a new control electronics, just like Alfa Romeo’s Bottas.
Regarding the gearbox units, Oscar Piastri is the sole driver to begin the Austrian Grand Prix weekend with a fresh gearbox cassette and gearbox driveline & auxiliary components.
With drivers allowed a maximum of four gearbox cassettes and internals for the entire season, the Australian still has one more fresh unit available for the remainder of the campaign.
